Further Challenges

• The line graph below shows the number of ticks eaten by Ollie in 4 minutes. How many ticks might Ollie have eaten in 90 seconds?

• Can you write a similar problem for a friend to solve that involves Ollie the oxpecker eating different numbers of ticks over time? What will the pattern to your number sequence be? Can you think of a pattern that no one else will have thought of?
• Tables Without Tens is a fabulous investigation on the Nrich website that will encourage you to notice patterns and make conjectures whilst revising your multiplication tables.
